The most comprehensive collection of knotting resources on the web. Sections on knot tying, mathematical knot theory, knot art, and knot books. www.earlham.edu/~peters/knotlink.htm
Has many beautiful images of symmetric knots, and information about a computer program called Knotscape (compiled binaries for Linux, Sunos and Alpha platforms). Includes pictures of knots with 13 crossings or less. www.math.utk.edu/~morwen
Has a large number of beautiful graphics of knots created with KnotPlot. Contains an introductory section on mathematical knot theory. KnotPlot software for various platfroms can be downloaded. www.cs.ubc.ca/labs/imager/contributions/scharein/KnotPlot.html
Includes examples, solutions, knot tables, pretty pictures. Course material includes: colouring, Alexander and Jones polynomials, tangles and braids. www.maths.warwick.ac.uk/~bjs/MA3F2-page.html
Starting with the flawed theory of Kelvin's knotted vortex to the work of Thurston, Jones and Witten, knot theory has circled back to its ancestral origins of theoretical physics. www.math.buffalo.edu/~menasco/Knottheory.html
High school level introduction to knot theory. Covers colourings, connected sums, torus knots, prime knots and applications of knot theory. www.bangor.ac.uk/cpm/exhib
Braidlink is software for knot and braid theory computations. It performs both analytic and numerical manipulations of knots and braids. www.knot-theory.org
Biographies of early knot theorists. Many early papers on knot theory (in pdf format) including papers by Tait, Kirkman, Little and Thomson. www.maths.ed.ac.uk/~aar/knots/index.htm
Comprehensive knot theory site focusing on the knot classification problem and knot tabulations. Has a tabulation of knots with up to 12 crossings. www.inst.bnl.gov/~wei/contents.html
A mathematical analysis of string figures. Theorems, examples, illustrations and conjectures on patterns created with an unknotted string. website.lineone.net/~m.p/sf/menu.html
A topologist working in knot theory discusses the connection between knot theory and statistical mechanics. Sections on cybernetics and knots, Fourier knots and the author's research papers. bilbo.math.uic.edu/~kauffman
A collection of knots and links, viewed from a (mostly) mathematical perspective. Nearly all of the images here were created with KnotPlot, a program to visualize and manipulate mathematical knots in three and four dimensions. www.pims.math.ca/knotplot
Thomas Fink and Yong Mao, used ideas from statistical mechanics to show there are 85 ways to tie a tie. They discovered a number of new aesthetically pleasing tie knots. This page has links to their original papers and to their book ``The 85 Ways to Tie a www.tcm.phy.cam.ac.uk/~tmf20
This site is designed for mathematics students at the high school and college levels as an introduction to an area of mathematics seldom explored in the typical math classroom - the Theory of Knots. www.freelearning.com/knots
